What material are Legion Cemented Stems made from?

• A. Titanium
• B. Aluminum
• C. Cobalt Chrome
• D. Stainless Steel

Answer: (C)

Cobalt-chromium alloy is chosen because it provides high yield and fatigue strength, excellent wear resistance, and strong radiopacity, all essential for a cemented femoral stem that must endure long-term loading while embedded in bone cement and remain visible on X-rays. Titanium and aluminum don’t offer the same combination of strength and wear properties for this cemented design, and while stainless steel is used in some implants, the Legion cemented stem specifically uses cobalt-chromium for its robust mechanical performance and imaging visibility.
